Once these pathways have been established, it is generally not possible to correct a lazy eye through any means (which includes laser eye surgery). Can laser eye surgery correct a lazy eye? If the balance is not redressed by this age it may be too late and the lazy eye will persist into adulthood.
However, by the age of seven some of the pathways that link the eye to the brain are fully developed. These refractive errors or misalignments can be treated effectively using glasses or patches designed to stimulate the weaker eye. If left untreated, this can develop into amblyopia over time. When does it occur?Īs mentioned above, roughly two or three children in every hundred are born with some kind of discrepancy with their eyes. This then causes the brain to favour the stronger eye, resulting in a loss of vision in the weaker eye over time. The second is when the eyes have differing amounts of refractive error, called anisometropia. The first is a misalignment of the eyes, known technically as strabismus. There are two primary causes of amblyopia. In that sense the terminology is a little misleading, as the condition has as much to do with neurological issues as the eye itself. What is a lazy eye?Įssentially, a lazy eye (the medical term is amblyopia) is caused when the eye and brain are not working properly together. In order to answer this question properly, it is necessary to understand exactly what we mean by a lazy eye, establishing the difference between this and other optical conditions. One question we’re frequently asked here at Optegra is whether laser eye surgery can correct the lazy eye and restore vision to normal. As one of the most common optical conditions, a lazy eye affects around 2 to 3% of children as they develop in their early years.
